The invention provides a label-following type digital paper tape cutting machine, and aims to solve the problems that a paper cutting machine in the prior art cannot automatically cut and is low in cutting precision.

As shown in fig. 1, the label-tracking type digital paper tape cutting machine provided by the embodiment of the invention comprises a frame 10, a paper feeding mechanism 20 and two paper cutting mechanisms 30, wherein the paper feeding mechanism 20 and the two paper cutting mechanisms 30 are sequentially arranged on the frame 10, the two paper cutting mechanisms 30 are arranged at intervals along a first direction, the paper feeding mechanism 20 is used for feeding a paper tape 40 to be cut into the two paper cutting mechanisms 30 along the first direction, so that the two paper cutting mechanisms 30 sequentially cut the paper tape 40 to be cut along a second direction, and the second direction is perpendicular to the first direction; the label-tracking digital paper tape cutter also comprises an electrical control system (not shown), and the paper feeding mechanism 20 and the two paper cutting mechanisms 30 are electrically connected with the electrical control system.

The first direction is the left-right direction in fig. 1, the second direction is the front-back direction in fig. 1, and the third direction is the up-down direction in fig. 1.

In this embodiment, since the two paper cutting mechanisms 30 are spaced apart along the first direction, when the paper to be cut 40 is transported along the first direction by the paper feeding mechanism 20, the first paper cutting mechanism 30 can cut the paper to be cut 40 first when passing through the first paper cutting mechanism 30, then the paper to be cut 40 after the first cutting is transported along the first direction under the action of the paper feeding mechanism 20, and then the second paper cutting mechanism 30 continues to cut along the cut after the first cutting when passing through the second paper cutting mechanism 30, so as to improve the cutting accuracy of the paper to be cut 40. The label-following type digital paper tape cutting machine can enable the paper feeding mechanism 20 and the two paper cutting mechanisms 30 to operate under the action of the electric control system, so that full-automatic cutting of paper labels is realized and the cutting efficiency of the paper labels is improved on the basis of ensuring the cutting precision of the label-following type digital paper tape cutting machine.

It will be appreciated that in other embodiments, the number of paper cutting mechanisms 30 may be one or more than two, so that the label-tracking digital paper tape cutter can also have different modes of cutting.

Meanwhile, referring to fig. 2 and 3, the label-following digital paper tape cutting machine further includes an identification mechanism 50, where the identification mechanism 50 includes a label-dividing identification sensor 51, a screw rod 52, a screw rod driving member 53, a screw rod nut 54 sleeved on the screw rod 52, and a baffle 55 mounted on the frame 10, the label-dividing identification sensor 51 is disposed on the screw rod nut 54 and electrically connected with the electrical control system, the screw rod nut 54 is slidably disposed on the baffle 55, and the screw rod driving member 53 is used to drive the screw rod 52 to rotate, so that the screw rod nut 54 drives the label-dividing identification sensor 51 to slide along the second direction. The identification patterns are arranged on the existing digital paper tape (to-be-cut paper tape 40), the identification patterns on the to-be-cut paper tape 40 passing through the paper feeding mechanism 20 can be identified through the signature identification sensor 51, the signature identification of the paper signature of the to-be-cut paper tape 40 entering the paper feeding mechanism 20 is judged, and the signature identification sensor 51 can control the running speeds of the two paper cutting mechanisms 30 and the paper feeding mechanism 20 through the electric connection with the signature identification sensor 51 according to the signature identification signals identified by the signature identification sensor 51, so that the signature type digital paper tape cutter can cut paper signatures of various different specifications, and the compatibility of the signature type digital paper tape cutter is improved.

Specifically, the signature recognition sensor 51 is a color patch sensor for detecting a recognition pattern on the sheet 40 to be cut, and performs color patch detection by comparing with a region on the sheet 40 to be cut where the recognition pattern is not present. When detecting, the light source of the color code sensor is perpendicular to the paper tape 40 to be cut, and if the color code sensor recognizes the recognition pattern on the paper tape 40 to be cut, the paper feeding mechanism 20 and the paper cutting mechanism 30 are controlled to start to operate by the electric control system of the color code sensor, and the paper tape 40 to be cut is cut. In the detection process, if the color code sensor does not recognize the recognition pattern on the paper tape 40 to be cut when recognizing the paper tape 40 to be cut, the electric control system controls the screw rod driving piece 53 to start working, and then the screw rod driving piece 53 starts driving the screw rod 52 to rotate. The lead screw nut 54 is slidably disposed on the baffle 55, so that the lead screw nut 54 can slide along the second direction with the color code sensor during the rotation of the lead screw 52, and the electrical control system controls the lead screw driving member 53 to stop working and enables the paper feeding mechanism 20 and the two paper cutting mechanisms 30 to start working and cut the paper cutting tape 40 when the color code sensor recognizes the recognition pattern on the paper cutting tape 40 during the sliding.

Meanwhile, in the preferred embodiment, the color code sensor can send different signals to the electrical control system according to the difference of the identified pattern intervals on the paper tape 40 to be cut, and the electrical control system can control the paper feeding mechanism 20 and the two paper cutting mechanisms 30 to cut at different speeds, so that the standard-following digital paper tape cutting machine can adaptively change according to the different specifications of the paper tape 40 to be cut, and the compatibility of the standard-following digital paper tape cutting machine is improved. Therefore, the label-following type digital paper tape cutting machine can be used for cutting the paper tape by tracking the cutting position of the paper tape, and the paper feeding mechanism is fed into the paper tape to form required signatures after being cut by the two paper cutting mechanisms 30.

Referring to fig. 1, 2 and 4, the paper cutting mechanism 30 includes a blade module (not labeled) and a knife pad module (not labeled) disposed on the frame 10, and the blade module and the knife pad module can cooperate with each other to cut the paper tape 40 to be cut along the second direction. Preferably, the blade module comprises a blade assembly 31 and a first driving member 33, and the knife pad module comprises a knife pad assembly 32 and a second driving member 34, and the first driving member 33 and the second driving member 34 respectively correspondingly drive the blade assembly 31 to rotate and the knife pad assembly 32 to enable the blade assembly 31 and the knife pad assembly 32 to mutually cooperate to cut the paper tape 40 to be cut along the second direction. When the blade module works, the electric control system controls the first driving piece 33 and the second driving piece 34 to work and drive the blade module and the knife pad module to rotate, and the blade module and the knife pad module can mutually cooperate to cut the paper tape 40 to be cut along the second direction in the rotating process of the blade module and the knife pad module. In another embodiment, the blade module is capable of cutting in a third direction (up and down in fig. 1), i.e., the blade module is configured to cut the tape 40 to be cut in a vertical direction when mated with the shim module.

Further, referring to fig. 5-8, the blade assembly 31 includes a blade unit (not shown) and a blade drum 311 connected to the first driving member 33, the blade unit includes a blade seat 312 disposed on the blade drum 311, a blade 313 disposed on the blade seat 312, and a first locking member 314 disposed on the blade seat 312 for locking the blade 313 to the blade seat 312; the shim assembly 32 comprises a shim unit (not shown) and a shim drum 321 connected to the second driving member 34, the shim unit comprises a shim seat 322 disposed on the shim drum 321, a shim 322 disposed on the shim seat 322, and a second locking member 324 disposed on the shim seat 322 and used for locking the shim 322 on the shim seat 322, and the blade 313 and the shim 322 cooperate with each other to cut the paper tape 40 to be cut along the second direction.

In this embodiment, the blade roller 311 drives the blade holder 312 disposed on the blade roller 311 to rotate, thereby driving the blade 313 disposed on the blade holder 312 to rotate, at this time, the blade pad roller 321 drives the blade pad holder 322 disposed on the blade pad roller 321 to rotate, thereby driving the blade pad 322 disposed on the blade pad holder 322 to rotate, and under the control of the electrical control system, when the blade roller 311 and the blade pad roller 321 rotate, the blade 313 and the blade pad 322 can simultaneously rotate to be located in the third direction, please refer to fig. 9, since the blade 313 rotates to be located in the third direction simultaneously in the process of rotating with the blade pad 322, at this time, the blade 313 is clamped into the blade pad 322, and since the to-be-cut 40 is located between the blade 313 and the blade pad 322, when the blade 313 and the blade pad 322 are matched, the blade 313 and the blade pad 322 are mutually matched to cut the paper tape 40.

Further, in this embodiment, the blade roller 311 is further provided with a height adjusting screw 316, and the feeding amount of the blade 313 and the shim 322 is changed by adjusting the height adjusting screw 316, so as to improve the matching effect between the blade 313 and the shim 322.

In addition, referring again to fig. 5, the blade assembly 31 further includes two pressing strips 315 disposed on the tool holder 312, wherein one pressing strip 315 is attached to one side wall of the blade 313 under the action of the first locking member 314, and the other pressing strip 315 is attached to the other side wall of the blade 313 under the action of the first locking member 314. Since the blade 313 is a hard alloy piece and is easy to fall off in the working process of the blade 313, the pressing strips 315 are arranged on the two sides of the blade 313, so that the blade 313 is not easy to fall off in the working process. And more preferably, the battens 315 are polyurethane battens 315, and the polyurethane battens 315 are capable of protecting the blade 313 when the blade 313 is used due to the fact that the polyurethane battens 315 have high flexibility and rebound resilience. In other embodiments, the bead 315 may be made of rubber, plastic, nylon, etc.

It should be noted that, the blade 313 of one paper cutting mechanism 30 includes a first blade body 3131 and a plurality of first blades 3132 disposed on the first blade body 3131, the plurality of first blades 3132 are arranged at intervals along the second direction to form a plurality of first spacers 3133, the blade 313 of the other paper cutting mechanism 30 includes a second blade body (not shown) and a plurality of second blades disposed on the second blade body, the plurality of second blades are arranged at intervals along the second direction to form a plurality of second spacers, the plurality of first blades 3132 are in one-to-one correspondence with the plurality of second spacers, and the plurality of first spacers 3133 are in one-to-one correspondence with the plurality of second blades. Meanwhile, the blade structures of the two paper cutting mechanisms 30 are the same, and only have certain dislocation, namely the blades of the two paper cutting mechanisms 30 are arranged in a dislocation way. Specifically, since the plurality of first cutting edges 3132 provided on the first blade body 3131 of one of the paper cutting mechanisms 30 are arranged at intervals in the second direction and form the plurality of first spacing portions 3133, the first cutting edges 3132 form only a plurality of spaced first cuts on the paper strip 40 to be cut when the first cut is made on the paper strip 40 to be cut. Meanwhile, because the second blades on the second blade body of the other paper cutting mechanism 30 are also arranged at intervals along the second direction and form a plurality of second spacing parts, and the second spacing parts are in one-to-one correspondence with the first blades 3132, that is, the first blades 3132 and the second blades are arranged in a staggered manner, when the paper tape 40 to be cut is cut by the first paper cutting mechanism 30 and then is cut by the second paper cutting mechanism 30, the second blades stagger the cut after the first cutting to form a second cut, and the first cut and the second cut are kept level, so that the cut after the two cuts together form a section to cut the paper tape 40 to be cut so as to realize complete cutting to form the required paper paste.

In the above preferred embodiment, however, reference may be made to fig. 6, in which the number of blade assemblies 31 is two, and the two blade assemblies 31 are symmetrically arranged. In this embodiment, the blade roller 311 and the shim roller 321 rotate once to cut twice when passing through the first paper cutting mechanism 30, and the blade roller 311 and the shim roller 321 still rotate once to cut twice when passing through the second paper cutting mechanism 30, and the blade roller 311 and the shim roller 321 overlap with the first cut surface, so that the paper tape 40 to be cut is cut into a paper label according to the requirement. And preferably the blade cylinder 311 and shim cylinder 321 are rotated 180 ° between the first and second cuts of the blade cylinder 311 and shim cylinder 321. In other embodiments, the number of degrees of rotation of the blade roller 311 and the shim roller 321 between the first time and the second time of cutting may be changed to accommodate different sizes of paper for cutting, while the number of blade assemblies 31 may be one or more than two.

Meanwhile, the paper feeding mechanism 20 further includes a second transmission assembly (not labeled), the second transmission assembly includes a third synchronizing wheel set 21 'and a fourth synchronizing wheel set 22' which are disposed on the frame 10, a third synchronizing belt 23 'and a third conveying belt 24' which are sleeved on the third synchronizing wheel set 21', and a fourth synchronizing belt 25' and a fourth conveying belt 26 'which are sleeved on the fourth synchronizing wheel set 22', the third synchronizing belt 23 'is further sleeved on the first synchronizing wheel set 21, the fourth synchronizing belt 25' is further sleeved on the third synchronizing wheel set 21', the third synchronizing wheel set 21' can be connected with the first synchronizing wheel set 21 through the third synchronizing belt 23', the fourth synchronizing wheel set 22' can be connected with the third synchronizing wheel set 21 'through the fourth synchronizing belt 25', and the third conveying belt 24 'and the fourth conveying belt 26' are mutually matched so that the two paper cutting mechanisms 30 sequentially cut the paper tape 40 along the second direction.

In this embodiment, the electric control system controls the fifth driving member 27 to start operating, and when the fifth driving member 27 starts operating, the fifth driving member 27 drives the first synchronous belt 23 to operate, and since the first synchronous belt 23 is sleeved on the first synchronous pulley set 21 and the second synchronous belt 25 is also sleeved on the first synchronous pulley set 21, the second synchronous pulley set 22 can be driven to operate by the operation of the first synchronous belt 23. At this time, the first conveyor belt 24 and the second conveyor belt 26 are respectively sleeved on the first synchronous wheel set 21 and the second synchronous wheel set 22, so that when the fifth driving piece 27 starts to work, the first conveyor belt 24 and the second conveyor belt 26 can be driven to start to operate. In addition, referring to fig. 4, during operation, when the paper tape 40 to be cut is conveyed along the first direction, the first conveyor belt 24 rotates counterclockwise, the second conveyor belt 26 rotates clockwise, and the conveying speeds of the first conveyor belt 24 and the second conveyor belt 26 are equal, so that the first conveyor belt 24 and the second conveyor belt 26 can rotate along the moving direction of the paper tape 40 to be cut, and thus no relative movement is ensured, and meanwhile, when the paper tape 40 to be cut enters the contact surface of the first conveyor belt 24 and the second conveyor belt 26, the first conveyor belt 24 and the second conveyor belt 26 can drive the paper tape 40 to be cut to continue moving, so that the smoothness of the paper tape 40 to be cut in the whole cutting process is maintained.

In operation, as the paper strip 40 to be cut is cut by the first paper cutting mechanism 30 and moves in the first direction, the third belt 24 'rotates counterclockwise, the fourth belt 26' rotates clockwise, and the conveying speeds of the third belt 24 'and the fourth belt 26' are equal, so that the third belt 24 'and the fourth belt 26' can move along the direction in which the paper strip 40 to be cut moves, and the second paper cutting mechanism 30 operates to cut the paper strip 40 to be cut in the second direction when the paper strip 40 to be cut moves in the contact surface of the third belt 24 'and the fourth belt 26'.
